A new standalone system for the tc, Proefi.
So a good friend of mine Jeremy of Garage1217 had a friend who wanted to test a new standalone system for the TC. Jeremy not having his Tc anymore, he gave me his friends number to call a guy name Jason Siebels. Not knowing who he really was i still took the offer of being the test car for his new project that he has been working on for 3+ yrs now.
So as i get my car towed to his house i notice a few nice cars out in his garage, a 240sx s14 and pretty well modded. so then we parked the tc in his garage i noticed a black supra. I asked Jason how fast did this thing run(in my head i was thinking maybe a 10sec) but he said 8sec(in my head ran the words F@$K thats fast, he gots me by 5 seconds in the TC lmao) so as i left he told me not to worry one bit about my car.
So as i drove home i decided to google his name and it came up mostly on car forums or car magazines. and damn i didnt know he helped build the AEM EMS and was one of the top EMS technicians. he was very popular in a lot of the supra forums and he owned his company is known as PROefi. I was pretty stoked that this guy was going to tune my car for me and fix up all the little problems with it. I read about his product and everyone seems to love his PROefi standalone system. So im right now im waiting to pick up my car(maybe tomorrow) and i will ask him more about the specs about this badboy. if you want to read more about the PROefi go to PROefi.com or if you want to watch some videos on youtube on some of his cars in action just type in PROefi as well.
well guys i will keep you guys more informed about the standalone once i get my car back. I CANT WAIITTT!!!!! also if you want to buy my greddy ultimate, and 07+ pnp harness check my FS link https://www.scionlife.com/forums/sho...d.php?t=170778

I have seen the first hand results, it is SICK! And the software is leaps and bounds ahead of anything I have seen before. All of the units are OEM quality build wise and will stand the test of time. I will be doing a pro-48 unit on my 93 mr2 turbo soon when other parts are completed on it! Just check the website for screen shots and so forth.
Also I hear of a lot of supra guys running it as well as the g&z crowd starting to pick up on it.
